Three crashes occurred Friday, Dec. 20, north of Crater Lake National Park due to slippery roads and vehicles stopped on the side of the road while their drivers were chaining them up.

Oregon State Police reminds people to use extra caution while driving on icy roads and during freezing rain, and to find safe places to stop when putting on chains.

The first crash of the day happened about 11 a.m. The driver of a commercial truck pulling two trailers loaded with lumber stopped on the side of Oregon 138 so he could chain up. The truck partially blocked the westbound lane. Nearby, two eastbound commercial trucks were also chaining up.

A truck pulling two trailers loaded with pears drove by and tried to make its way between the stopped trucks. But its rear trailer began to slide sideways and crashed into the side of one of the stopped trucks, nearly hitting the driver.

Another crash happened about 11:15 a.m. on Oregon 230, along the western edge of Crater Lake National Park. A truck pulling a semi-trailer stopped so the driver could chain it up. Shortly after, a Toyota pickup came around a curve. The driver, Michelle Zablan, 22, of Buena Park, Calif., lost control of the vehicle and crashed into the semi-trailer. Zablan and two adult passengers were taken by ground ambulance to a Medford hospital with non-life threatening injuries.

A third crash occurred about 2 p.m. near the intersection of Oregon 62 and Oregon 230. A driver lost control of an eastbound vehicle, which went across the road and over an embankment. The car stopped against some trees 50 feet down the embankment. The driver and the passenger were not injured.
